ORE DRIER AND $EPARATOR.

SPECIFICATION forming part of Letters Patent No. 294,157, dated-February 26, 1884.

Application filed June 30, 1883. (No model.) a

1"; all whom it may concern.-

Be it known that I, ALBERT SENEFF, of Laramie City, in the county ofAlbany and Territory of \Vyoming, have invented a new and Improved OreDrier and Separator, of which the following is a full, clear, and exactdescription.

My invention consists of improved apparatus for slowly passing the oredown a heated shaft or flue'of a furnace by devious courses on pans ordisks that have a slight shaking motion for distributing, agitating, andurging the ore forward, from which the ore is discharged upon alongsloping and graduated screen, to be graded and discharged into differenthoppers, from which each grade is passed separately through a conductorand falls past or through ablast of air from a blow-pipe supplied by abellows, by which the earth and other matters are blown away, while theore falls into receptacles provided for the different grades, all ashereinafter fully described, and particularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of my improved drier and separator. Fig. 2is a longitudinal sectional elevation. Fig. 3 is a sectional plan viewof thedrier on line 00 00, Fig. 2. Fig. 4 is an end elevation, and Fig.5 is a transverse sectional elevation online 3 y of Fig. l.

A represents a furnace of cylindrical form, on the top of which is acylindrical case or tube, B, resting on a ring, F, and forming aheat-flue, through which the products of combustion escape upward fromthe furnace. \Vithin this case B, I have arranged a series of sheet-ironhoppers, a, with intermediate conical disks, H, on a vertical shaft, G,the hoppers discharging at the center onto the disks, and the disksdischarging from their outer edges into the hoppers, for causing the.ores to traverse to and from the center and circumference of theheat-fines, for producing the best effects of the heat within thesmallest space for drying purposes. The disks are attached to the shaft,and the hoppers are connected to the disks for support by the rods orThe shaft Ghas a step in a cross-bar,

bars L.

b, at the top of the furnace, and it passes through a cross-bar, c, of aring, K, at the top of case B, for its upper support. Ahopper, I, with asloping screen, d, for a bottom, is located on the top of shaft G by ametal socket having a set-screw, J to secure the hopper in any desiredradial direction. Below the lowest hopper a the shaft G passes through aspout, E, into which said hopper discharges the ore to be conducted fromthe drier into the separator, said spout being inclosed in ajacket, c,which isemployed to lessen the loss of heat through the spout E,and-particularly to inclose a space wider than said spout E, in whichthe spout vibrates to impart a slight forward and backward motion to thehoppers and disks of the drier, to prevent the ores from lodging on themand to cause them to feed properly. The shaft has a collar, f, in spoutE, that is connected to the bottom plate of said spout E by the plate 9and lugs or bars 71, projecting from said collar and attached to saidplate 9, the spout E extending out of the drier and intothe separator,and through a notch in the upper edge of a sliding bar, 0, suitablyarranged in cleats attached to the end of separator-frame G, for beingshifted forward and backward by connecting-rod N and the cranked disk Mto vibrate said spout, and thus cause it to shake the hopper and disks.The screen din hopper I is to separate any coarse matters too large topass through the drier and separator and discharge them onto the ground.In practice it will be detachably connected to hopper I, in order thatinterchangeable screens of different mesh may be applied as may berequired. The spout E discharges onto the long sloping grading-screen Q,of five different sections and discharging into five different hoppers,\V. This screen is arranged over a series of knifeedged scrapers, V,arranged lengthwise of it, and placed about as far apart as the screenshifts in shaking, and with their upper edges touching the screen, toforce up any lumps or other matters lodging inthe screen, to prevent itfrom being choked and clogged. This screen rests on the friction-rollersz, fitted on studpivots attached to the frame, and is connected to thevibrating lever B by the rod j to be operated, said lever B being workedby the studpin in the side of cone-pulley S, acting on the shoulders Zof the yoke m of said lever, embracing the main driving-shaftn of themachine. The lever B is pivoted on the countershaft 1) for its fulcrum.From the series of hoppers V the different grades of ore fall into acorresponding series of shaking-spouts, X, to be discharged at the endsof said shakers, so as to fall into the receptacles D, the fallingstreams passing a series of blowrpipes, 0 from which they are treated toairblasts Which strike them directly under the bottoms of the shakersand free them of all light dirt and other matters of less specificgravity than the ores by the same being carried beyond the re ceptaclesD, While the ores fall into them. The air for this purpose is suppliedto the trunk by a pair of bellows, Y, located above the screen Q, andoperated by the sliding bars a, rock-lever A, pitman, cranked disk (1,belt 15, and the pulley u on the drivingshaft it. These bellowsdischarge the air into a pressure-reg ulai'or, Y, for steadying theblast, from which the air passes by the conductors B to the trunk 10.From the trunk 20 the air passes intoa chamber, b, for each blast-tubethrough an orifice, a, regulated by a valve, E, and a thumb-screw, d, tovary the force of the blast, the thumb-screws extending out through thecase of the trunk 10, Where they can be manipulated by the attendant atwill. The shakers are attached to a bar, 0, arranged for Jul sliding ina way, T, and having a lever, F", connected to it, said lever beingpivoted at h fora fulcrum, and being worked by the grooved cam G and astud-pin of said lever extending into the groove of said cam.

This cam is fitted loosely on the main shaft 72, and is driven bycounter-shaft p, cone-pulleys t" and j, and belt k, the cone-pulleysbeing employed to vary the speed of the shakers as may be required. Thecone-pulleys S, by which the screen Q is operated, are also driven byshaft 1), belt Z, and cone-pulley m, to vary its speed also. Thiscounter-shaft p is driven from the main shaft n by a belt, a, andpulleys, for the purpose of driving the shakers and screen as above.

The drier is designed to stand at one end of the separator, and isconnected to it by hooks D, for steadying one by the other.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the hopper I, screen (1,hoppers a, conical disks I-I, shaft G, heatilue B, and vibrating spoutE, as and for the purpose described.

2. The combination of the spout E, jacket 0, sliding bar 0, shaft G, thehopper, and the disks, as and for the purpose set forth.

3. The combination, in an ore-separator, of the sloping graded andshaking screen Q, series of hoppers XV, shakers X, blow-pipes c, andreceptacles D substantially as described.

4. The bellows Y, regulator Y, conductors B and the air-trunk w, incombination with the blow-pipes c, shaking-spouts X, and the receptaclesD", substantially as described.

ALBERT SENEFF.
